Description générale

Lycopene is a naturally occurring red pigment, which belongs to the family of carotenoids. It is found in tomatoes, watermelon and papaya. Lycopene has antioxidant property.[1]

Application

Lycopene has been used:
  • in high performance liquid chromatography (HPLC) to determine its concentration in liver, kidney and lung tissue[2]
  • to induce urokinase plasminogen activator receptor (uPAR) IN prostate cancer cell line[3]
  • in Raman chemical imaging system to detect and visualize its internal distribution[4]

Actions biochimiques/physiologiques

Antioxidant micronutrient of tomatoes associated with decreased risk for cancer and cardiovascular disease. Enhances gap juction communication between cells via upregulation of connexin 43 and reduces proliferation of cancer cells in culture. Inhibits cholesterol synthesis and enhances low-density lipoprotein degradation.
